Meanwhile, Eyre is expected to release her upcoming sophomore album – featuring the Fransisca Hall-assisted / Jesse Shatkin-produced lead single “Ego” – later this year via Universal Music Group / Virgin EMI Records.

Production duties on “Dark Four Door” were handled by Mike Crossey, whose resume boasts further works with Take That (“River”), Kaleo (“Way Down We Go”), The 1975 (“Love Me”), Wolf Alice (“Giant Peach”), Twenty One Pilots (“The Judge”), Imelda May (“Tribal”) and Amber Run (“Spark”).

The British singer/songwriter – born Ella Mary McMahon – dubbed “Ego” as the first promotional cut from her upcoming sophomore album and will release it later this year via iTunes and all other digital streaming outlets.
